Cannot find a primary authoritative dns server

This is my first time asking a question. This forum is awesome. I mostly find answers by looking through previous posts, but this one has the best of me. I think I have read and tried all the solutions on this problem.

netdiag gives me this error:

[WARNING] Cannot find a primary authoritative DNS server for the name
'____.com.'. [ERROR_TIMEOUT]
The name '___________.com.' may not be registered in DNS.

when I ran netdiag /v I also found this:
DNS test . . . . . . . . . . . . . : Failed
Interface {EBD23B86-4C6D-4FD0-A775-E6DF851FA7A8}
DNS Domain:
DNS Servers: 0.0.0.0

As you can see, the DNS domain is blank, ip is 0.0.0.0.

I have deleted the _msdcs.domain.com and repopulated, did not help

It seems that the dns server itself is not properly registered in active directory.

I have also disabled IPv6

I appreciate your help

Chris, no interfaces with {EBD23B86-4C6D-4FD0-A775-E6DF851FA7A8} , but I will try disabling others. There's Toredo Tunneling and Automatic Tunneling. Not sure how to disable but Ill try..

wow, I almost can't believe it. Thank you Chris. You got me on the right track. I completely removed IPv6 protocol, which removed the 2 tunneling devices I mentioned earlier. No more DNS issue. I had previously unchecked IPv6, but removing it completely fixed the problem.

I spent so much time trying to figure this one out.

thank you!
